Second parameter set (SET)
With function SET you can activate the second parameter set
through one of digital inputs 1 to 5.
When the SET signal is active, the frequency inverter works with
the characteristic of the second parameter set. You can use this
function, for example, to run a drive with two different
acceleration and deceleration times or operate an additional
motor using the same frequency inverter (although not at the
same time) without having to reconfigure the inverter.
Applications with one frequency inverter and two motors can
include:
• Roller drives vertical sorting systems in horizontal conveying
systems
• Rotation and traction drives of hoisting systems
The functions of the second parameter set are listed in Table 28,
page 85.
X Configure one of the digital inputs 1 to 5 as SET by entering the
value 08 under the corresponding PNU (C001 to C005).
The motor must be at a stop before the SET input is enabled.
As soon as the SET input is deactivated, the parameters of the
default parameter set are used again.
Special functions in the second parameter set (SP-SET)
With function SP-SET you can activate the second parameter set
through one of digital inputs 1 to 5 with modified authorization
levels.
The following example illustrate the possible uses for this
parameter changeover function for various deceleration ramps.
h
The changeover between the parameter sets can take
place only at standstill (STOP).
In the second parameter set, a 2 is appended to the
parameter’s group letter (PNU x2xx).
In the tables in this manual, the parameters of the second
parameter set have a grey background ( ).
